# TrademarkMind > Free trademark research tools built on the full USPTO register and the WIPO Madrid international register. Search existing marks, compare a logo against registered ones, check whether a brand name is available, and see what actually happens to applications after they are filed. Run by an independent developer, not a law firm. Nothing on the site is legal advice. ## What the data covers - 14.3 million US trademark records from the USPTO bulk feed, last synchronised 2026-10-19 - 2.8 million international registrations from the WIPO Madrid system, updated daily - 2,186,662 Canadian trademarks from CIPO open data, updated weekly (name checks and logo search) - 4.5 million mark images indexed for visual similarity search - Complete USPTO file histories, which is what powers the outcome figures below ## Figures you will not find elsewhere Across the 2,204,883 US applications filed between 2015 and 2019, 61.5% ended up registered, 58.4% drew at least one Office Action, and 34.8% of the applications that drew one were abandoned because nobody answered it.
